Miley Cyrus Tweets Photo of Engagement Ring?

Miley Cyrus recently uploaded a photo of what appears to be an engagement ring onto her Twitter account, and fans are now speculating whether or not she and Australian actor, Liam Hemsworth, are engaged.

"They're still keeping it a big secret, but they're seriously talking marriage. Liam is crazy about her!" a source told OK! Magazine.

"Miley wants the whole nine yards as far as a big wedding goes," the source said about the couple's reported engagement.

The 19-year-old "See You Again" singer tweeted a picture of a large clean cut diamond ring that she was wearing on her ring finger, although the couple has not confirmed whether or not they are engaged.

"I am soooo obsessed with @jennahipp nail foundations! It looks so chic and classic!" Miley tweeted, alongside the picture of her left hand.

Cyrus, who is the daughter of country music star Billy Ray Cyrus, reportedly met Hemsworth on the set of their 2010 film, "The Last Song," and the pair have been dating ever since.

Less than one year after they began dating, the couple split after after the "The Hunger Games" actor reportedly grew tired of her hard partying, according to X17 Online.

The two pair soon appeared to be together again after allegedly taking a break and have been together ever since.

"They are madly in love and inseparable," a source once told Hollywood Life adding that Miley, "thinks Liam is the one!"

While the couple may be engaged, some fans fear that Cyrus' partying is again starting to pose problems for Hemsworth.

"She gets pretty crazy. She's always out in skimpy outfits and writhing on (Liam). Sometimes he looks embarrassed for her," a source told US magazine.

The source claims that whenever the couple enjoys a night out, Hemsworth constantly becomes increasingly "concerned" about Cyrus' partying.

"Liam's always looking after her," the source said.
